U-series dating is a family of methods which can be applied to different materials over different time ranges.Each method is named after the isotopes measured to obtain the date, mostly a daughter and its parent.The scheme has a range of several hundred thousand years. Ionium–thorium dating is a related process, which exploits the insolubility of thorium (both Th is a constant during the period when the sediment layer was formed, that the sediment did not already contain thorium before contributions from the decay of uranium, and that the thorium cannot migrate within the sediment layer."Uranium–thorium dating has an upper age limit of somewhat over 500,000 years, defined by the half-life of thorium-230, the precision with which one can measure the thorium-230/uranium-234 ratio in a sample, and the accuracy to which one know the half-lives of thorium-230 and uranium-234.

Rb-Sr is a good example for explaining the process, however.
This of course contradicts claims that the Great Flood messed up how carbon was deposited, destroying their own argument.
Less astute creationists often conflate carbon dating with other forms of radiometric dating, attempting to "disprove" the true age of dinosaur fossils by "refuting" carbon dating.
Meteorites are among the oldest objects we know about - formed about 4.5 billion years ago. This article describes the principles and methods used to make that determination.
There are well-known methods of finding the ages of some natural objects.
Simply counting the number of rings will give one a fairly good idea of the age of the tree.
